,To all whom it may concern.-

Be it known that I, KARL WESSEL, a subject of the German Emperor,residing at Lan sing, in the county of Cook and State ot Illinois, haveinvented certain new and useful Improvements in Hay-Curlin g Machines;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to a novel construction in hay curling machinesand has for its object to provide a device of this character, of simpleand durable construction and which will curl or crimp the hay in aneffectual manner.

The invention consists in the features of construction and combinationsof parts hereinafter fully described and specifically claimed.

In the accompanying drawings illustrating my invention,-Figure 1 is anend elevation of the same. Fig. 2 isa vertical cross section. Fig. 3 isa vertical longitudinal section. Fig. i is a fragmentary detail view.

Referring now to said drawings, A and B indicate the end frames orstandards of the machine which are suitably connected and bracedtogether by two beams 1. About midway between the upper and lower endsof the standards A and B are located the journal bearings or boxes 2that are adapted to receive the hollow journals 3 and i upon the end ofa cylinder 5. These hollow journals 3 and 4 communicate with theinterior of said cylinder 5 and serve to permit the ingress and egressof steam. The said journals 3 and a extend beyond the bearings 2, andthe journal 3 is provided thereat with a drive pulley 6` or the meansfor'rotating the same. A steamsupply pipe 7 communicates with the end ofthe hollow journal 3, and a stuffing box 8 serves to form a tightconnection between said pipe 7 and journal 3. In this way it will beseen steam can be admitted to the said hollow journal and to theinterior of the cylinder 5.` It will, of course, be understood that Ican employ a different medium for cylinder, but I have found steamconvenient and preferable. The journal i at the other end of thecylinder communicates at its outer end with an outlet pipe 9 and isprovided with a stuffing box 10 to form a tight joint therewith, in anobvious manner. The construction of said cylinder 5 is as follows: Twohollow disks 11 that are connected and communicate with thejournals 3and 4 serve to form the ends of said cylinder, and said disks areconnected with each other by a hollow cylindrical casing l2 joined atits ends to said disks as shown in Fig. 3. A series of openings orperforations 13 are made in 4the periphery of each of said disks so thatthe perforations in eachv disk are in alignment with each other. Aseries of pipes 14 are provided with inwardly bent ends 15 and theseends are inserted within the openings or perforations 13 in the hollowdisks, and secured in such a manner as to make a steam tight jointtherewith. In this way it will be seen that the pipes 14 will stand awayfrom the face of the cylinder, but parallel therewith, as shown in Figs.2 and 3, and that the entire face of the cylinder will be provided withthe laterally projecting pipes 14. The said pipes 11i are supported sothat they will stand at all times parallel with the face of the cylinderby bars 16 that extend between said pipes and the face of the cylinderand from one end of the cylinder to the other, so that said pipes willbe braced along their entire length, as will be manifest. Locatedbetween each of said lines of pipes and extending the whole length ofthesame is a 'series' of grooved or transversely curved gutters 17. Thesegutters 17 are secured along their side edges to the pipes 11i and serveto produce in eect a corrugated cylinder or a cylinder having a seriesof grooves and intervening ribs or ridges.

To the top of the standards A and B, and concentric with the journals ofthe cylinder, are arranged a plurality of journal bearings or boxes 18.The said boxes or bearings 18 are located within guides 19 that arereadily arranged with relation to the cylinder, and the said boxes 18have a sliding connection with said guides and are controlled by twoscrews or bolts 2O and 21 arranged respectively above and below saidboxes 18 and bearing against the same, so that by suitably turning saidscrews or bolts the bearings 18 IOO can be nicely adjusted. Said boxes1S at 'each end of the machine are arranged in alignment with each otherand receive the journals 22 and 23 on the ends of the pressure rollers24. A plurality of these pressure rollers 24 are employed, as shownfinFigs. 1 and 2, and they are disposed about the cylinder as shown. Eachof said pressure rollers 24 is constructed as follows: Connected andcommunicating with the hollow journals 22 and 23 are the hollow disks 25and 26 which are "connected with each other by a pipe or tube 27, andsaid pipe or tube 27 is smaller than the disks 25 and 26, so that saiddisks project beyond the same. Uponl the inner faces of said disks 25and 26 a series of perj forations or openings are made which receive theends of pipes 28, as clearly shown in Fig. 3. The said pipes 28 arelocated parallel with the face of the tube 27 and are supported in thisposition by bars 29 that extend the entire length of said tube 27.Located between each of the pipes 28 is a transversely grooved or curvedcutter 30 which is secured along its edges to the pipes 28, as clearlyshown in Fig. 4. The said pressure rollers 24 are so disposed withrelation to the cylinder 5 that the grooves and ridges on saidpressurerollers will intermesh or interiit with the grooves and ridges on thecylinder, so that as said cylinder is turned it will in turn rotate saidpressure rollers upon their journals. The devices for introducing steamor other heating medium into said pressure rollers are constructed asfollows: The said hollow jour nals 22 and 23 extend beyond their bearingboxes and the journal 22 communicates with an inlet pipe 31 forsupplying steam thereto. A stuihng box 32 serves to form a tight jointbetween the inlet pipe 3l and the said journal. Each of said inlet pipesis connected by a radial pipe 34 to astufting box a on the curved pipeb, to allow longitudinal movement of said pipes 34 when it is desired toadjust the small pressure rollers 24. The other hollow journal 23 of thepressure rollers con1- municates with an outlet pipe 35, and a stuftingbox 36 is employed to make a tight connection between these parts. Thesaid outlet pipes 35 are similarly connected by radial pipes 34 tostuing boxes aon a curved pipe b for the same reasons. In this way itwill be seen that hot steam is admitted through the hollow journal 22and disk 25 to the pipes 28 of the pressure rollers, so as to heat thesame, while at the same time steam is admitted to the pipes 14 of thecylinder to impart heat to these pipes.

As shown in Fig. 1 a shelf or table 37 is secured between the standardsA and B of the machine just below the first of the series of pressurerollers and formsat-able or platform upon which the hay can rest whilebeing fed into the machine. Just below the last of the series ofpressure rollers, and on the other side of the machine, is arranged adelivering roll 38 which is preferably ribbed, as shown,

and upon which the hay will fall and be de-1 flected outwardly, in anobvious manner.

TWhen the hay is to ybe curled it is fed across the table 37 in a moistand dampened condition, while at the same time the pipes of the cylinderand pressure rollers are heated by the passing of steam therethrough andthe cylinder is rotated. As the hay is fed between the I'irst of theseries of pressure rollers and the cylinder it will be caught betweenthesame and moved or fed along so as to pass between each pressureroller and the cylinder. The hot pipes serve to dry the moisture out ofthe hay, and by reason of the intertting pipes and the corrugated formof the cylinder the hay will also be curled or crimped and pressed intothe desired condition and will emerge in this condition from the lastpressure roller.

It will, of course, be 'understood that the gutters or curved piecesbetween the pipes 17 and 28 serve to prevent the hay from enteringbehind these pipes and clogging the ma-y chine, and it will also benoted that in ac'- cordance with the principle involved by my inventionI contemplate omitting such gutters it' it is found desirable, whereuponthe supporting bars 16 and 29 which support the pipes 14 and 28 willserve to prevent the hay from clogging behind the said pipes.
